Form Construction 1. Set forts to required grades and lines, rigidly braced and secured. 2. Install sufficient quantity of fors to allow continuance of work and so that forms remain in place a minimum of 24 }tours after concrete pplacement. 3. Check completed formwork for grade and alignment to following tolerances: Top of farms not more than 1/8" in 10' -0 ". Vertical face on longitudinal axis, not more than 1/4" in 10' -0". 4. Clean forms after each use, and coat with for release agent as often as required to ensure separation from concrete without damage. B. Reinforcement: Locate, place and support reinforcement per Division 3 specifications. C. Concrete Placement 1. Comply with requirements of Section 03300. 2. Do riot place concrete until base material and forms have been checked for line and grade, Moisten base material h required to provide uniform dampened condition at time concrete Is placed. Concrete shall not be placed around manholes or other structures until they are at the requlrer: dntsh elevation and alignment. 3. Place concrete using methods which prevent segregation of mix. Consolidate concrete along face of fors and adjacent to transverse joints with internal vibrator. Keep vibrator away from joint assemblies, reinforcement, or side forms. Consolidate with care to prevent dislocation of reinforcing, dowels, and joint devices. 4. Deposit and spread concrete in continuous operation between transverse joints, as far as possible. If Interrupted for more than 1/2 hour, place construction joint. D. Joint Construction: Construct expansion, weakened-Vane Control (contraction), and construction joints straight with face perpendicular t concrete surface. Construct transverse joints perpendicular to centerline, unless otherwise detailed. 1. Weakened -Plane Control (Contraction) Joints: Provide joints at a spacing of 15' -0" o.c. maximum each way. Construct control joints for depth equal to at least 1/4 concrete thickness, as follows: a For tooled joints in fresh concrete by grooving top portion with recommended tool and finishing edges with jointer. b. Form sawed joints using powered saws equipped with shatterproof abrasive or diamond - rimmed blades. Cut joints Into hardened concrete as soon as surface will not be tom, abraded, or otherwisedamagod by cutting action. 2. Construction Joints: Place concrete joints at end of placements and at locations where placement operations are stopped for period of more than 1/2 hour, except where such placements terminate at expansion joints. Construct joints using standard metal keyway- sectlon forms. 3. Expansion Joints: LoGlte expansion points at 180' -0" o.c. maximum each way. Provide premolded joint filler for expansion joints abutting concrete curbs, catch basins, manholes, inlets, structures, walks, and other fixed objects. E. Joint Fillers: Extrid joint fillers full -width and depth of joint, and rot less than 1/2" or ,more than 1" below finished surface where joint sealer is indicated. If no joint sealer, place top of joint filler flush with finished concrete surface. Furnish joint fillers in one -piece lengths for full width being placed, wherever possible. Where more than one length is required, lace. or clip joint filler sections together. F. Joint Sealants: A!I joints shall be sealed. Exterior pavement joint sealants shall be insta: ., ;; r marrnfacurer's recommendations. 3.03 CONCRETE FINISHING A. After striking off and consolidating concrete, smooth surface by screening and floalhrr. Adjust floating to compact surface and produce uniform texture. After floating, test surface for trueness with 10' -0" straightedge. Distribute concrete as required to remove surface irregularities, and refloat repaired areas to provide continuous smooth finish. 02520-3 April 8, 1993 r w. ....y .,_,.,,.,,.. «e;.us . _ ..,., —- -•we. a ea.J,a' . ,„,,,,r,,,Y„ .,,,.,a,.b. ,..<. . , _. _, <:.. 1.'.. , 1.U i.el1 a ,uw.r wr.-'• _. ..._. -... .-_J a., _..
